液晶显示器以其微功耗、体积小、显示内容丰富、超薄轻巧的诸多优点，在袖珍式仪表和低功耗应用系统中得到越来越广泛的应用。 这里介绍的字符型液晶模块是一种用5x7点阵图形来显示字符的液晶显示器，根据显示的容量可以分为1行16个字、2行16个字、2行20个字等等，这里以常用的2行16个字的1602液晶模块来介绍它的编程方法。 -LCD display with its micro-power consumption, small size, display rich content, ultra-thin lightweight many advantages, in the pocket instrumentation and low-power applications are more and more widely. Here introduce the character LCD module is a 5x7 matrix used to display graphics characters liquid crystal display, according to show that the capacity of one line can be divided into 16 characters, 2 lines 16 characters, 2 lines 20 characters and so on, here commonly used 2 lines 16 characters LCD module to the 1602 introduction of its programming method.

芯片PCF8951共有四个A/D输入通道：AD0，AD1，AD2，AD3,分别与四个电位器(R1,R2,R3,R4)连接，用以调节电位器的输出电压。其中AD0通道既可测量电位器输出电压，也可用于测量从J1插座输入的外接电压，须用开关J2加以选择。J4插座提供由PCF8591输出的时钟方波信号。SAA1064驱动四个数码管显示一路AD转换后得到的数据。-PCF8951 chip, there are four A/D input channels: AD0, AD1, AD2, AD3, respectively, with four potentiometers (R1, R2, R3, R4) connected to regulate the output voltage potential. AD0 channel which can be measured potentiometer output voltage can also be used to measure the input from the J1 socket external voltage, to be used to select switch J2. J4 socket output from the PCF8591 clock square wave signal. SAA1064 drivers of four digital display along after AD conversion data.
